Abstract: A dam portion (200) includes a wall surface positioned along an edge of the organic film and faces the display area. The substantially rectangular shape is a rectangle including a side along a first direction and a side along a second direction perpendicular to the first direction and including a chamfered portion (210) forming an outline inclined to the first and second directions. The wall surface (200w) includes first partial wall surfaces (200x) along the first direction and second partial wall surfaces (200y) along the second direction. The first partial wall surfaces (200x) have a length that is an integer multiple of a first unit length, and the second partial wall surfaces (200y) have a length that is an integer multiple of a second unit length. In the chamfered portion (210), the first partial wall surfaces (200x) and the second partial wall surfaces (200y) are connected in a zigzag manner.

Abstract: A method of manufacturing a display device, includes steps of forming a first inorganic film, forming a first organic film so as to cover the first inorganic film, removing a part of the first organic film, forming a second inorganic film so as to cover the first inorganic film and a region of the first organic film that has not been removed in the step of removing the part of the first organic film, forming a second organic film so as to cover the second inorganic film, removing a part of the second organic film, and forming a third inorganic film so as to cover the second inorganic film and a region of the second organic film that has not been removed in the step of removing the part of the second organic film. A thickness of the first organic film is different from that of the second organic film.
